The control-tower supervisor who failed to respond to two planes trying to land at Reagan National Airport outside Washington, D.C., has been suspended while the Federal Aviation Administration investigates.

The controller was the lone person on duty in the tower after midnight and had fallen asleep, an anonymous aviation official told The Associated Press.

The two at-risk airliners contacted the regional flight dispatch center and landed safely within minutes of each other.
